i develop an app, which tracks gps points and i show these points on my MapView (lets say this is "Activity1"). I can start a second Activity ("Activity2") where i can add some descriptions to the newest gps point. If i close Activity2 and "go back" to Activity1, all my overlays arent display any more. How can i save the overlays??
Must I add all my GPS points to an array an save this array in my onSaveInstanceState() method (because i cant put a List<Overlay> object in the onSaveInstanceState method) and read this array back, if i come back to Activity1 (onStart or onResume??)??
Thanks in advance,
